1/7 MOJAVE 6S V2 4WD BLX Desert Truck with Spektrum Firma RT

The 1/7 scale ARRMA® MOJAVE™ 6S BLX 4WD Desert Truck RTR is ready for big bashing action on any terrain. Its Spektrum™ SLT3™ 3-channel radio, dual protocol receiver, Smart ESC and more combine to reach new levels of speed, toughness and versatility.


ARRMA engineers have updated the MOJAVE 6S BLX 4WD Desert Truck with a brushless power system featuring the Spektrum Firma 150A Smart ESC and Firma 2050Kv brushless motor. The combination lets you cut loose with incredible torque, acceleration and speed, while the heavy-duty aluminum and steel chassis and transmission components take it all in its stride. For improved steering, ARRMA® also includes a new, steel gear Spektrum™ S652 Digital Servo — which is 32% stronger and 5% faster than the previous version's ADS-15M servo.

The ready-to-run package now also includes a 3-channel Spektrum SLT3 radio and Spektrum SR315 dual protocol receiver. Perfect for long hours of fatigue-free bashing, the transmitter's ergonomic design features a foam steering wheel for precise fingertip control and an improved hand grip and trigger feel. If you're a new driver, you'll be able to set throttle limits at 50% or 75% until you're ready to use the full speed potential. The SLT3™ is compatible with Tactic® SLT™ receivers to run other RTR vehicles you may own, and includes a third channel to control optional features such as lights and winches on models that have them.

Because the SR315 receiver can use SLT™ and DSMR® protocols, you can easily upgrade to a Spektrum™ DSMR® transmitter later — then, download the free Spektrum™ Dashboard™ app for your mobile device and take full advantage of the Smart telemetry capabilities already present in the Firma™ electronics. You'll be able to receive real-time updates of ESC temperature, receiver (BEC) voltage, drive pack voltage and motor RPM.

With the rugged construction of the MOJAVE™ 6S BLX 4WD Desert Truck, you'll have the strength needed to survive anything — bashing through dirt, asphalt and grass, in sun, rain or snow. The tough-as-nails anodized aluminum chassis is reinforced with front, rear and center braces for maximum durability. Bumpers and nerf bars supply impact protection on all sides. Thanks to independent suspension with bump-soaking oil-filled shocks, the Desert Truck handles equally well over wicked and well-travelled tracks.

The drivetrain is a masterpiece of heavy-duty design. Featuring steel driveshafts, metal gears, and all-metal diff outdrives, it's ready to take full advantage of the brushless power system's potential. As it comes out of the box, the MOJAVE™ 6S BLX Desert Truck is incredibly fast. Use a 6S LiPo with the optional pinion gear upgrade (gear is included), and the resulting 60+ MPH speed potential is enough to crush any competitor. Keeping your truck in top form is easy. A sliding mount gives you access to the motor in seconds. You can remove the center diff for maintenance by taking out just five bolts.

Multi-terrain dBoots® FORTRESS™ tires on multi split-spoke wheels give your MOJAVE™ 6S BLX Desert Truck the grip to get up, over, or through anything in your way. And it doesn't just perform like a winner. It looks like one, too, with a painted and decaled desert truck body, color-coordinated roll cage and roof rails, and even a detailed cockpit.

I really hope that the 1/7 4WD SCT class becomes a thing and this make 4S a standard for the 4WD SCT class going forward!

Just to be clear, isn't this essentially a 1/8 Typhon???

Have you seen my LVC?
No, this truck actually has a longer wheel base than a 1/8 Truggy. Width, it is about an inch wider than the Typhon (1/8 Buggy). Stock tires are just a bit smaller than racing truggy tires, so they can work, with a bit of body trimming.

Over on the Arrma Forum, several folks have done a chassis swap, Kraton to Mojave, to make a extra-long wheel base truggie. Add hex extenders, and a 4985/1717 size motor, and you have a beast of a basher.

Oh, and I didn't see it announced here yet, but there is a EXB version of the Mojave coming soon (pre-order now). Sold as a Roller, with full 7075 aluminum parts, upgraded diffs and other goodies. Plus a much better factory paint job...

Dang, didn't realize it was THAT big, not sure they would let this class run at any 1/8 tracks in our area

Thornhill seems to be a pretty big track, Seems it could work. But yeah, it is big...

Even if they did let them run with the Truggy class, what kind of tire selection are we talking about?
Nov 08, 2020, 11:36 AM
Have you seen my LVC?
Minor body trimming, and Truggy tires will fit. So tire selection becomes the same as Truggy.
